Alan Turing Honored As The Face of the UK's New 50-Pound Bank Note
The Bank of England has unveiled the new 50-pound note featuring mathematician and computer science pioneer Alan Turing, who helped the Allies win World War II with his code-breaking prowess but died an outcast after facing government persecution over his homosexuality. NPR reports: The bank revealed the note's design and features -- which include a number of clever visual references to Turing's work -- on Thursday, nearly two years after first announcing that it would honor Turing. The banknote will officially enter circulation on June 23, Turing's birthday. Andrew Bailey, the governor of the Bank of England, noted in prepared remarks that Turing is arguably best known for his code-breaking work, which historians credit with shortening World War II by about two years and saving millions of lives. But far beyond that, he said, Turing's pioneering work in computing and artificial intelligence "has had an enormous impact on how we all live today." Instead of paper, the new note is made from polymer, which is longer-lasting and harder to counterfeit. It completes the bank's "family" of polymer banknotes, Bailey said, joining the Winston Churchill 5-pound, Jane Austen 10-pound and J.M.W. Turner 20-pound. The note itself features an image of Turing and his signature as it appeared in a 1947 visitor's sign-in book on display at Bletchley Park Trust, where he worked during the war. It includes a quotation, taken from a 1949 interview in which Turing was speaking about his ground-breaking Pilot ACE machine, one of the world's first computers: "This is only a foretaste of what is to come and only the shadow of what is going to be." Symbolic designs on the note include a mathematical table and formulae from Turing's 1936 paper "On Computable Numbers, with an application to the Entscheidungsproblem," technical drawings of the British Bombe code-breaking machine and ticker tape depicting his birth date in binary code. A sunflower-shaped foil patch, containing the initials "AT, "represents Turing's work in morphogenetics, a branch of developmental biology focused on the algorithms behind patterns occurring in nature. It's another scientific field for which Turing helped lay the groundwork, Bailey noted.Read more of this story at Slashdot.
